50 ILCS 725/7.2

An employer of an officer shall not make possession of a Firearm Owner's Identification Card a condition of continued employment if the officer's Firearm Owner's Identification Card is revoked or seized because the officer has been a patient of a mental health facility and the officer has not been determined to pose a clear and present danger to himself, herself, or others as determined by a physician, clinical psychologist, or qualified examiner. Nothing in this Section shall otherwise impair an employer's ability to determine an officer's fitness for duty. On and after August 17, 2018 (the effective date of Public Act 100-911), Section 6 of this Act shall not apply to the prohibition requiring a Firearm Owner's Identification Card as a condition of continued employment, but a collective bargaining agreement already in effect on that issue on August 17, 2018 (the effective date of Public Act 100-911) cannot be modified. The employer shall document if and why an officer has been determined to pose a clear and present danger.
